The reason for spacing the pinsgirregu larly is to cause each pin in each group to. 7

travel along a separate path With the result that, supposing the hackles to 'e be" ar. T ranged in groupsof8j withfl2pinsin'eaeh i pins Will describef96 separate} v v pitching of the f paths of the hackle pins throughthe flax can in 6 or 8 instead of 12 or 24. This shorter grouping permits of time. for at least one hackle of each kind in the group to pene trate the flax during each lift and thus all portions of the flax get hackled. WVhen the hackles were grouped in 24 then 24 bars had to pass before a hackle of each sort had penetrated the flax, and for this reason many parts of the piece never received hackling until they had passed the first or second sets of hackles.

In the example shown in Fig. 1, the hackles indicated by the horizontal lines have their pins indicated by the circles arranged in groups of 8 as indicated by the dotted lines A indicating the'distance be tween thenarrower spaced pins, B thedistance between the wider spaced pins and P the pitch, and it will be seen that by spacing the intermediate pins a irregularly as shown in Fig. 1 each such pin will intersect a space with the result that twice as many hackling paths are obtained in Fig. 1 as are obtained by the existing method of spacing as shown in Fig. 2, in which the pins are arranged in groups of four as indicated by the dotted lines, although the pins number the same in the aforesaid figures.

In the ordinary method of hackling all portions of each individual piece of flax do not receive equal pinning, owing to the fact that the flax in descending and rising has in itself a motion relative to the motion of the pins, so that each succeeding hackle striking into the descending or rising material, travels a path differing in dimensions from that travelled by its immediate predecessor. Owing to the grouping, the striking in'points during the fall and rise lie along a line'whlch forms an angle (depending on the grouping) with the horizontal, and or-' din'ates drawn from the striking in points to the horizontal represent the path of each pin through the flax. During the dwell th striking in points he along the horizontal,

and their path through the flax isindicated by lines drawn at right angles to the horizontalthus those portions of theflax subjected 'to treatment by the pins are clearly outlined, while the spaces on which no lines appear. show those portions ofthe material which pass on to the following tools, without having been touched by the pinsat all. The percentage of such spaces'to the total area of the flax is, under ordinary conditions,

undesirably large. The above is'illustrated' in Fig. 3 which shows the portions of a piece of flax which receive hackling duringone complete movement of the channels with the machine running at 8 lifts per minute and the sheets revolving at 12 revolutions per minute, the hackles being groupedin 24. C indicates the length of the holder. D the length of the fiax, the points were the pins strike into the flax. are indicated by the circles E, the hackling that is done during the dwell of the channel is shown by the dotted lines F; the hackling that is done.

during the fall of the channel is shown by the dotand dash lines G; the hackling that is done during the rise of the channel is shown by the full lines H; and the unhackled portions of the flax are represented by the blank spaces J. V

\Vhat I claim as myinvention and desire to secure by Letters Patent in the United States, is: V I A hackling machine having a series of hackles each provided with a row' of pins, the pins of the successive hackles being ar ranged in diagonal paths, and said paths I have. signed this specification.
